Abstract (en)
[origin: EP1126310A2] A multifocal refractive contact lens for focusing light on the retina of the eye comprises a plurality of segments, one of the plurality of segments being a first segment having a first, distant optical power, and another of the plurality of segments being a second segment having a second, near optical power. The second segment is located adjacent the first segment and forms a boundary therewith. The lens is non-oriented and the segments have substantially spherical surface curvatures and are radial segments with boundaries formed along arcuate, radial paths from the centre of the lens to the circumferential edge. <IMAGE>
